At present, what methods do we take to solve the attack? The first method shortens the waiting time and deletes the illegal request data packets waiting in the waiting queue as soon as possible. The second method is that the first handshake message is not put into the waiting queue. We return a 32-bit unsigned integer to the client as the Seq of the second handshake. The integer is obtained by adding a serial number of the server to the parameters requested by the user (including the requested address, port, etc.). If it is a normal user, it adds 1 as ACK after receiving this integer and returns it to the server. After receiving the data, the server subtracts 1 from this ACK and then performs inverse operation to obtain various parameters. Finally, the data sent out are compared. If they are completely consistent, it means that it is an effective response and stored in the corresponding data structure, otherwise it is not. Through this method, illegal requests cannot occupy system resources.那道院墙是内院墙，墙外面是过道，过道另一边的大院墙才是外院墙。随即，会稽山中出现盗匪息传遍了山yīn城。Setting position, configuration type (referring to portable type, cart type, etc.), quantity, production date and drug replacement date.他气度非凡，一开口便威势逼人，绝非童侍郎可比，公堂上下霎时落针可闻。扔掉的白绢就落到项伯的席位之旁，项羽伸手捡起来，瞧了一眼，看到玉玺几个字眼的时候，心头不由的猛然一震。《大人物李德林》是根据河北作家何申的６部中篇小说改编而成的，是一部具有扎实生活基础的24集电视连续剧，它通过县、乡、村三级干部在工作和生活中产生的矛盾、纠葛，结构成一环扣一环的故事，塑造出一批具有时代精神，又奋进向上的、真正为老百姓谋幸福的好干部形象。在一波三折的情节变化中，透视出当今现实生活中人与人之间微妙、复杂、多变的人际关系。
